Meiling Cu-Au deposit, Hami (Kumul; Qumul) Co., Hami (Kumul; Qumul) Prefecture, Xinjiang (Xinjiang-Uygur) Autonomous Region, China

Located in the Paleozoic uplift along the southern margin of Tuha basin in eastern Xinjiang, in the superimposed Mesozoic volcanic basin upon the northern part of the Late Paleozoic Dananhu-Tousuquan accretionary arc. The deposit is controlled by NWW-, SN- and EW-trending faults. Host rock is mainly a rhyolitic-dacitic ignimbrite, but Cu-Au mineralization is closely related to quartz porphyry, rhyolitic porphyry and granitic porphyry. Ore-forming styles are dominantly veinlet-disseminations and veinlets, and occasionally stockworks. Hydrothermal alterations are mainly silicfication, sericitization, alunitization, pyrophyllitization, illitization, hydromuscovitization and chloritization.
